10 a/.ZZ whom, it may concern:

Be it known that we, THOMAS FRANKLIN and GEORGE L. 'BELDING, citizens of the United States, residing at West Point, in the county of Orange and State of 'New York, have invented new and useful Improvements in Peeling-Machines for Vegetables, of which y the following is a s l eciication.

Our invention re ates to a potato-peeler of new and improved construction whereby a large number of potatoes or other vegetables may be rapidly and thoroughly peeled and cleaned with the minimum of waste.

The important features are a hollow base having a bottom inclined toward the center and a spout to collect and deliver the waste peel to drain, &c.`

water. containing` the dirt and particles of On the base is set an `inclosing shell, referably of sheet metal, and within the she l is secured the (perforated cylinder, roughened `or rovide with projec-` tions on its inner su ace to abrade the sur-` 'and are peculiarly disk is firmly secured in faces of' the potatoes, as hereinafter described. Within the cylinder is journaled a suitable supportinor frameor spider, on which the dis perforated androughcylinder.- he disk and spider are preferably made convex, as shown, Withxaslight downwardinclination toward their periphery constructed, so that Athe lace without unde-fV sirableprojections, which) tend to collect the peelings, l dirt, &c. MeansV are rotating the disk at a considerab rovided for espeed. 'A

. ystream of water is directed into the top of the cylinder'to wash the potatoes.

'An important feature is a door in the cylinder, so formed and arranged that when opened inwardly' the peeled and cleaned otatoes are'quicklv and conveniently de` Evered outwardly 'through a corresponding opening and a chutewithout stopping the machine. y

Both the cyiinderand disk must be perforated to ermit the waste to iiow away and be-suitab y roughened on their inner surfaces to abrade or pick ofi the skins. These thin metallic parts may be perforated and provided with desirable interior projections by punching the parts from the exterior with a suitable tool. A desirable form of machine madeaccording to our invention is shown in the drawings herewith, in which the reference-letters of the speciiication indicate the same parts in all the figures. l

Figure 1 is a top lan of our machine with the door open an 'a portion of the disk broken away. Fig. 2l is a vertical section. Fig-3 is a' lan of the disk detached. Fig. l is a parta section of the disk and s ider er1-- larged. Fig. 5 is a partial vertica section showing the door o ien.- Fig.l 6 isa partial elevation showingt e door closed. Figs. 7 and 8 are respectively plan and edge viewsof a section of a desirable form of perforated cylinderand disk.

In the figures, 1 indicates the base, provided with integral bearings- 2 2 and 3 for the shafts and withsupporting-lugs 4 4 for the shell and the cylinder. Tric bottoni ofthe base is preferably inclinodvtoward the center, whereby 'the Washing-waterv is conveniently collected and delivered throughthe waste-spout G at; one side to alreceptacle yor drain. The base may b e bolted on suitable supporting-legs 7 7, and the form thereof (best-shown in Fig. 2) affords a solid for the parts.

In the bearings 2 2` are journaled the driv- .ing-shaft 10, carrying the power-pulley 11 and the idler 12, connected by miter-gears 13 support to the counter-shaft 14, journaled in the central .bearing 3 and supportino1 on its upper end the spider, composed of the central hub 16 and the radiating arms 17, on which is se cured by hooks 18 and ,clamping-plate 19 the peculiarly-formed disk 21. A ball-bearing` 2() may be used. Power may be applied in any other suitablel manner. This disk'must be perforated and formed with suitable picking projections on its upp'erOr interior surface, by which the skins are abraded or picked off progressively, but very rapidly. These maybe called the operative projections, and it is desirable to have none other in the interior, such as screw-heads, which would tend to catch the dirt and fragments of skin. We have therefore devised a simple construction and means for clamping the disk firmly in `place without undesirable projections. The disk is formed of sheet'metal` (more or less resilient) having a central opening and marginal notches to fit the hooks 18, secured to the ends of the arms 17 and split at 22,-

Ioo

.whereby tinJ circumferential length of the j disk may be shortened by drawing the split j Vand having an annular ends together. The disk is then set in place on the spider, its edge pressed out under the hooks, preferably beveled to bind, as shown in Fig 4, and then clamped securely in place by the clamping-plate 19, screwed to the hub shoulder or tiange 24 toengage with the inner edge ofthe disk. As best shown in Fig. 4, this shoulder is merely thick enough to form an abutment Vfor the disk edge, but is thinner than the disk, net to interfere with the secure clamping thereof. The only screws are those in the clampingplate, and they are therefore arranged where they can be countcrsunk and where there is the, ininirniini of contact with the moving potatoes. The use of screws securing the disk directly to the arms is thus avoided.

One of the arms 1.7 islslotted longitudinally at 27and thc slit 22 between the disk ends is arranged -to register Vith this slot, whereby the waste water and particles are not caught, but are free to ilow out through said slot ain slit. As shown, the disk and spider are made convex-that is, higher at the center, with a slight inclination toward .the sides whereby the outward movement and circulation of the potatoes is assisted. If the centrifugal force of the disk were alone relied on for suoli outward movement, an excessive speed might be necessary, and this would not Only be a waste of power and a strain on ihe parts, but would cause the potatoes iiioi'e or less to 'cling to the cylinder and not circulate.

On the lugs 4 is supported and secured by any suitablevmeans, such as angle-irons 3l), the cylinder 81, perforated and provided with internal projections like the disk and ot' a diameter only slightly greater than the disk that there may be rather a close tit.`

33 is the inclosing shell to retain the water, which is preferably merely set in place on the lugs so that it can be removed readily. The shell and the cylinder may he` 'l their upper margins reinforced, as shown.

The shell is provided with an opening 35, and at this point a frame 37 is bolted to the base and is provided with a chute. 34, having sides 36 to deliver the potatoes out through said opening. In said trame is hinged a suitable door 40, carrying a stop-arm 39, so arranged that when the door is swung in it is stopped at the proper angle. On the inner surface of the door is secured the piece 38 of curved and perforated sheet metal eut from the cylinder to fori n the opening, corresponding to shell-opening 35; Then the door is open, the rotating potatoes strike its outer surface to be directed out through the chute and are thus quickly ejected and the machine emptied ready for a fresh charge. Asshown in Figs. l and 6, the door-liii'igcs 41 are ar' ranged out of vertical alinement to maintain thetiower edge of the door substantially paralj li i i l l l i l i tl l \ be observed-without stopping lel to the inclined disk surface as it is swung' in. The direction of rotation of the disk is indicated the arrow in'Fig. 1.

Figs. 7 and S show, enlarged or exaggerated, a desirable form of perforated picking )rejections These are preferably formed by punching' in the infetal from the exterior with a tool of triangular or other suitable shape. A perforation so made increases in diameter outwardly, so that the particles of skin and dirt easily pass out. By this construction thc skins are removed in tine particles, so that they are easily washed out with the dirt through the holes and the potatoes thoroughly washed while being peeled. 5() indicates a spout of any desirable form, through which the washing-water is introduced.

The disk and cylinder are desirably iiiade of hard steel, so as to resist the wear, but are arranged easily t-o be removed and replaced when the projections are worn down.

Our machine is simple and economical to construct and to operate and from its various 'features peels and cleans the potatoes rapidly and effectively and with the smallest possible waste. The operation iiiay easily the machine and the. potatoes removed `ls soon as their light color indicates thatthey are peeled and cleaned.

While the machine is described 1n connecit may be uscdfor tion with otatoes," yet and fruits.

cleaning ot er vegetables compressed air for cleaning where water would be unnecessary or undesirable.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
